RECOMMENDED OPERATING CONDITIONS
over operating free-air temperature range (unless otherwise noted). The functional performance of the device specified in this
data sheet is achieved when operating the device within the limits defined by the Recommended Operating Conditions. No
level of performance is implied when operating the device above or below the Recommended Operating Conditions limits.

(1) Voltages VCC, VREF, VOFFSET, VBIAS, VRESET are required for proper DMD operation. All voltages referenced to VSS (ground).
(2) Exceeding the recommended voltage difference between VBIAS and VOFFSET may result in excessive current draw.
(3) See System Interface Load diagrams on the next pages.
(4) Optimal, long-term performance of the Digital Micromirror Device (DMD) can be affected by various application parameters, including
illumination spectrum, illumination power density, micromirror landed duty-cycle, ambient temperature (storage and operating), case
temperature, ambient humidity (storage and operating), and power on/off duty cycle. TI recommends that application-specific effects be
considered as early as possible in the design cycle. Contact your local TI representative for additional information related to optimizing
the DMD performance.
(5) As measured between any two points on or within the package including the mirror array. See the Thermal Characteristics for
information related to calculating the micromirror array temperature.
(6) Landed Duty-Cycle refers to the percentage of time an individual micromirror spends landed in one state (+12° or -12°) versus the other
state (-12° or +12°).
